PukiWiki wiki engine. The developers (and the homepage) are Japanese, but there is information in Englishhere. The hompage used be at 'PukiWiki.org', but unfortunately that domain name was accidentally lost and is now a pointless domain parked website, however, the software can be downloaded from the SourceForge website at – http://PukiWiki.sourceforge.jp, along with its new homepage at – http://PukiWiki.osdn.jp. The home wiki is: PukiWiki.

PukiWiki is written in PHP, with plain text file-based storage. Binary data can be attached to any page. "slash" divides content into directory-like hierarchy. Icons at the bottom right provide wiki commands and features, e.g. for RecentChanges click the clock icon ()
